OFFICE OF NAVAL RESEARCH (March 5, 2009) The U.S. Navy is converging two separate research efforts â unmanned air vehicles (UAVs) and fuel cell systems â to significantly improve battlefield surveillance capability. The Ion Tiger is a hydrogenpowered fuel cell UAV in development at the Naval Research Laboratory, the corporate laboratory of the Office of Naval Research (ONR). Previously flown with battery power, it has demonstrated sound aerodynamics, high functionality, and low-heat and noise signatures. When the final test flight of Ion Tiger lifts off, it will demonstrate how an enduring surveillance solution can operate at a low cost with less possibility of detection. The trial is expected to exceed previous flights seven-fold, from a duration of over three hours to 24 hours, while carrying a payload of 5 lbs. (U.S. Navy video/Released)
A Versatile Heli-UAV Program
While perusing the many sights and sounds of the 2008 Heli-Expo, ANN's Aero-TV crews got a look at an intriguing helicopter-based UAV program with a number of missions applications and capabilities. Call the CybAero 'Vantage', this UAV is a vertical take-off and landing (VTOL) unmanned helicopter developed by US Naval Research Laboratory (NRL). With fully autonomous flight operation and differential GPS navigation, CybAero claims the Vantage can perform a wide variety of missions in both military and commercial applications.
The Vantage is powered by a specially configured UEL 801 42-HP heavy-fuel (JP5, JP8, Jet A) rotary engine, utilizing an electrically driven ducted tail rotor, powered by an onboard starter/generator. This configuration saves weight and mechanical complexity. The overall fuselage length is 112 inches with a rotor diameter of 109 inches. CybAero utilizes a foldable tri-blade system making the Vantage HMMWV-transportable. It has a gross weight of 380 ...
